FHP CA CONSOLE series Installation Instructions Manual - page 2
970-293 Revised 05-12
INTRODUCTION:
The FHP console water source heat pumps are designed
for use as decentralized room terminals that are field
connected to a closed-circuit piping loop within a
structure. Typically these units are installed in perimeter
zones and are ideal for installations where ducted systems
are impractical.
All FHP Console Series units are designed for boiler/tower
systems geothermal closed loop applications and can
operate with fluid temperatures as low as 25°F in heating
and as high as 110°F in cooling. Units are available in 3/4,
1, 1-1/4 and 1-1/2 tons nominal capacity in cooling. Refer
to the unit specification sheet for precise performance
figures at various entering air and water conditions.
NOTE:
Console units are designed for indoor installation
in the conditioned space only. Do not install outdoors, in
attics or in any other location that would subject the unit to
extreme temperature or humidity or to corrosive
environments. Doing so will inhibit performance, reliability
and service life of the unit.
SAFETY CONSIDERATIONS:
Installation and servicing of this system can be hazardous
due to system pressure, electrical components and
moving parts. Only trained and qualified service
personnel should install and service this equipment.
Untrained personnel can perform basic maintenance such
as cleaning coils/cabinet or replacing filters.
WARNING:
Before performing service or maintenance
operations on system, turn off main power to unit. On
units with unit mounted controls, the On/Off switch DOES
NOT disconnect the unit from main power. High voltage
components or moving parts can cause injury or death.
When working on this equipment, always observe
precautions described in the literature, tags and labels
attached to the unit. Follow all safety codes. Wear safety
glasses and work gloves. Use a quenching cloth for
brazing operations and place a fire extinguisher close to
the work area.
This unit is designed to be operated with the cabinet,
subbase and filter in place. Never operate unit without the
cabinet and filter in place or with open access panels.
Doing so can expose the operator to hazardous voltage
and moving parts and can damage the equipment.
INITIAL INSPECTION, MOVING
AND STORAGE:
Inspect the carton or packaging of each console unit as it
is received at the job site and before signing the freight
bill. Note any damage or shortage on all copies of the
freight bill. Concealed damage must be reported to the
carrier within 24 hours of receipt.
Unit wiring diagrams and Installation/Operation manuals
are provided with each unit. Read these manuals prior to
start up to become familiar with the unit and its
operation.
Note that an Installation/start-up checklist is provided at
the end of this manual to encourage thorough unit check-
out at start-up.
Take care when moving the unit as most of the unit's
weight is located on the left (compressor) end. Always
store and move unit in an upright position. Take care to
protect the unit cabinet and subbase when moving or
storing. Never move or lift unit by its water connections.
If the equipment is not needed for immediate installation,
it should be stored in its original packaging in a clean, dry
area. Units must be moved and stored in an upright
position, never lay the unit on it's side. When storing, do
not stack units.
INSTALLATION:
Before installing the unit, examine each pipe, fitting and
valve; remove any dirt or debris found on or in these
components. Use care when installing the system
components to avoid damage to the cabinet finish or
chassis.
1.
After removing the console unit from its packaging
remove the cabinet by removing the cabinet screws
on either side of the unit and lifting the cabinet off
the chassis. Set the cabinet aside and cover it (the
console unit’s packaging can be used for this
purpose).
2.
Position the sub base directly on the finished floor.
Make sure the sub base is level (use shims if
necessary). The sub base has a frame that supports
the cabinet and may be secured to wall.
3.
Position the chassis onto the sub base. Check and align
electrical, water and condensate connections and
secure to the sub base with 4 screws.
4.
Before connecting the unit to water, make sure that
the loop has been properly flushed. After flushing the
system, connect piping or hoses to the proper supply,
return and condensate connections. Refer to the
piping section of this manual for more information
5.
Make all necessary electrical connections to the unit.
Refer to the unit wiring diagram and the Electrical
section of this manual.
CAUTION:
When making electrical connections to
the unit make sure that the power is disconnected.
Failure to do disconnect power before connecting
power wiring to the unit can result in serious injury or
death and damage to the unit.
6.
Make sure the unit’s washable filter is clean and
installed in the subbase. Also make sure that the filter
clip is in place.
7.
Reinstall the unit cabinet via locating pins at the top
of the chassis and two screws in the unit subbase.
